yi ,osaeoa Specification of Letters Patent.

vthe structure shown being characterized by an absence of means whereby the passage ot' air through the burner structure is prevented.

The principal object of the invention is to provide a gas burner and water heater, preierably ol" integral construction, the embodiment of the invention' shown making provision for the utilization of heat below the burner openings as well as along the sides thereof.

One embodiment o'f the invention is disclosed in the structure illustrated in the accompanying drawings, in which like characters of reference indicate corresponding parts in all the views, and in which-M Figure 1 is a side view showing the burner adapted to an ordinary stove; Fig. 2 is a top plan View of the burner, partly sectional; Fig. 3 is a sectional view on the line 3--3 of Fig. 2; while Fig. -il is a similar view on line 4 4 of Fig. '2 with the inlet water pipe removed.

The combined burner and heater is especially adapted for use with a supporting structure 1 of any desirable size and term, provided with the usual manifold 2 and gas cock l3, the burner 4 conmiunicating with a reservoir 5 through the pipes 6 and 6a provided with valves 7 and Te. l

Referring particularly to Figs. 2, 3 and 1- it will be noted that the burner and heater is substantially of integral construction, circularV in outline, and is provided with a number of upstanding walls 8, l), 10, 11 and 12, the walls 8 and 9, together with the top and bottom portions ot the burner, forming a passageway 13, the walls 10 and 11, together with the top and bottom portions of the burner, forming a passageway 14- incommunication with the passageway 13 through the intermediate passageway 15. The upstanding wall 12 incloses a passageway 1G having another passageway 17 leading there from, whereb the circulation of Water through all t e passageways is provided.

Adjacent the under side of the burner and heater is a chamber 18 providedwith the gas' inlet 18a adapted to be connected to the supply of gas, the top wall of the said chamber being provided with a mimber of burner openings 19; it will be noted that the heat radiated by the burning gas at these opere ings 1s prevented from escaping downwardly, being utilized in the heating ot water within the passageways, a supplv ot air to these burners independently 'et'` the mixing fluid comprised within the gas cock 3 being unnecessary. There are preferably two cireularrows of these burner openings 19, although it is obvious that in the event of making large burners and heaters various numbers ol' rows of openings may be pron vided.

Referring particularly to Fig. 3, it will be noted that one side of the burner and heater, that is, the passageway 13 adjacent that side, communicates with the reservoir 5 by means of the pipe G; it will also be noted that the central chamber 16 'of the heater communicates with the reservoir 5 through the lower pipe 6S1 and a short pipe G extending through the gas chamber 18 into the said central chamber, the burner structm'e being preferably provided with threaded openin s 20, 20a for the reception ot' the threaded ends of .the said pipes t3 and 6e. In order to pro vide for blowing out the heater or cleaning it, the under side is preferably provided with an outlet 21, closed by means of a removable plug 22.

In the use of the device, after the gas has been lighted at the burner openings, the water from the reservoir passes through the lower pipe 6, thence through the inner passageway 1G, then into the second passageway 14, through the intermediate passagefway 17, finally passing into the outer passageway 13 through the passageway 15, then leaving the burner through the pipe entering the threaded shoulder 20 and baclrto the reservoir. This relative positioning of the pipes for the circulation of the water, together with the particular relation ol the passageways among themselves, prevents the` burner and heater becoming steam-bound when in use; the maximum amount of heat given by the gas at the burner openings 19 is availed of both in heating material*v eontained in any vessel. placed on theburner,

and also in heating the water Within'the A.

burner, since the absence of openings or ernia` municating means between the space beneath the burner and that above provides for the absence of drafts which tend to carry away the heated air.

In stoves of some size a number of these burners may be used, and they may be connected together to form a battery1 whereby the Water within the reservoir 5 may be heated, the number of burners Working at any one time being not dependent on the burners not Working at that time.

Having thus described my invention, what l elaini as new and desire to secure by Letters Patent is:

l. A gas burner and water heater, cornprising va body having a plurality of annular communicating Water passages spaced from each other to iorm annular passages open at the top, the innermost Water passages being at the center of the body, a gas chamber on the under side of the body and having in its top burner openings leading into the spaces between the water passages, a Water inlet leading into the innermost water passage, and an outlet leading from the outermost water passage.

Q. A gas burner and water heater, comprising a body having a plurality of annular communicating water passages spaced from each other to form annular passages open at the top, the innermost water passage being at the center of the body and communicating with the intermediate passage at a point diametrieally opposite the communication between the said intermediate and outermost passages, a gas chamber on the under side of the body and having in its top openings leading into the open top passages, a Water inlet leading through the gas chamber and extending into, the innermost water passage, and a Water outlet leading from one side of the outermost water passage.

3. A gas burner and Water? heater, coinprising a body having a, plurality of annular communicating water passages and intervening annular passages `open at the top, the innermost Water passage being at the center o the body, a gas chamber on the under side of the body and communicating With the open top passages', a Water inlet leading through gas chamber into the innermost water passage, a Water outlet leading from the side of the outermost Water passage, a blow-oft' opening in the bottom of the outermost passage, and a plug for closing said opening.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
